EAST Northants MP Louise Mensch is due to quiz News International bosses over the phone hacking scandal today.

News Corporation chairman Rupert Murdoch, his son James, chairman of News International and former chief executive of News International Rebekah Brooks will face questions from the Culture, Media and Sport Select Committee.

Mrs Brooks, 43, resigned on Friday and was arrested on Sunday on suspicion of corruption and in connection with phone hacking and then released on bail. She is due to appear before the committee at 3.30pm, with the Murdochs expected to face the committee at 2.30pm.

Conservative MP Mrs Mensch yesterday refused to comment on the committee session, described as one of the most important of modern times.

She said: “I am very happy to speak afterwards but not before. It would not be appropriate.”

Doubts have been cast over how much information Mrs Brooks will be able to offer MPs following her arrest.

On Twitter, Mrs Mensch said: “Our legal advice is we are still expecting Mrs Brooks and that questions will be carefully drafted not to tread on the police investigation.”

John Whittingdale will chair the panel and among those sitting with chick-lit author Mrs Mensch will be MP Tom Watson who led the outcry against News International and the phone hacking scandal.

Last week on Newsnight Mrs Mensch challenged the Murdochs to “show leadership” and appear before the committee to answer questions about the scandal and she told ITN it was important someone from News International spoke up, saying: “It would show a little bit of leadership, it would be the first step in lancing this giant boil.”

On Twitter she has spoken in favour of a self-regulated press but said the Press Complaints Commission needs “more teeth”.

With the world’s eyes on today’s committee, she took time yesterday for relaxation, tweeting: “Nothing like a good run for stress relief round beautiful Oundle.”
